PLOW-LAY.

Specification of Letters Patent.

Patented June 20, I1911.

having a removable portion or lay provided witha point, andthe two portions of the plow having parts of special construction and particular arrangement for securing them together withouty using bolts near the point of the plow where they would be hardto reach and diicult to remove.

The special construction constituting 4this invention is illustrated in the accompanyingV drawings, of which- Figure llrepresents a side view showing the two portions separated. Fig. 2 is a perspective rear view and shows all 4parts assembled. Fig.3 is a perspective rear view, showing the two portions separated.

The same letter is used to refer to the same part throughout'the drawings and the description.

The mold board is designated by the reference letter A, and the landsideby letterB. Toward the point of the plow the landside liastwo recesses. One recess is a large triangular recess, and the 'other is a smaller recess. The larger recess is marked C and the smaller recess which opens into the larger recess is referred toI by the letter D. These recesses will be` again mentioned.

As best shown in Fig. 3, it will be noted that the mold board has a projecting portion E extending downwardly from its lower edge and .usually formed integrally with it. The edge of the projecting portion E engages the removable portion of the invention as more fully explained below.

The two portions of this invention require only the single bolted plate or strap F having the bolts f all within easy reach for y removal. The bolts pass through the plate F, and through the mold board A and the lay Gr.

In Figs. 2 and 3 it is shown that the lipm thev that is formed near the upper edge ofthe lay G on the rear of the-lay, leaves a space between it andthe lay into which the edge of the projecting portion E on the rear side'- of the mold board fits. These parts are constructed very strong, and they take up practically all the strain that is exerted against the other side of the mold board and lay, and there is relatively no force thrown upon the bolted plate connection F.

To hold the plow point rigidlyj in its proper position, when the two portions are brought together from their separated attitudes as shown in Fig. 3, 'the triangular pro-A jecting portion c fof the lay G engages the recess C,and the wedge-shaped block d engages the recess D, at the same time the lug H is inserted into the slot h in the butN tom of the recess C, as bestlshown in Fig. 1. In constructing this invention, the parts are made to tit well. Thus, the edge of the pro- Aes,

jecting portion E in rear of the ,mold board fits closely the space between the lip e and the rear surface of the lay, and the parts c, d, and H, fit the recesses C, D, and the slot It. When the two portions are assembled,
